ments in headlights and refers more particularly to an adjustable support for the socket for an incandescent lamp for the purpose of bringing the. incandescent film in line with the focal axis or the reflector.

In other words, my object is to provide for the axial and radial adjustment of the lamp relatively to the reflector.

Other specific objects will be brought out in the following description.

In the drawings-Figure 1 is a front elevation of a portion of a headlight-case showing my improved adjusting means for the lamp, a portion of the lamp socket being shown inoperative position. Fig. 2 is a diametrical sectional view of the headlight showing the incandescent lam in elevation. Fig. 3 is a perspective view 0 the detached lam supporting bracket.

T 1is headlight comprises essentially a circular case -1- having a movable closure -2- covering the open side of a reflector -3 and provided with a transparent glass 'front 4- substantially co-extensivc with the area of the open side of the reflector and co-axial therewith. An angular bracket -5- is secured by suitable fastening means, as screws -6-, to the back of the casing -1 ncauonc side, and preferably near the hinged side'of the door 2- for receiving and supporting the incandescent lamp socket --7- carrying an incandescent lamp having an incandescent fil1n-(-,oil 9-- adapted to be brought (to-axial with the reflector by the adjustment of the bracket itself upon the back of the case -l--. The lamp socket -7- is adjustably secured by suitable las toning means, as screws idwhich are assed through elongated slots in the i moans lor scrurmg the reflector to the bac racket 5- to permit the lamp and its supporting socket to be adjusted parallel with the axis of the reflector to bring the coil '9' into proper relation with said reflector. In like manner, the apertures through which the fastening means pass are elongated radi- 5? ally of the case and reflector having slots cess to the 12' to permit the radial adjustment of the bracket *5' with the lamp ---8 thereon for the purpose of bringing the incandescent coil -9 into the axis of the reflector, it being understood that the intensity of the reflected light depends largely u on the position of the incandescent coil of the lam with reference to the axis and apex of the reflector, and the essential feature of my invention resides in providing means whereby the lamp may be adjusted radially and axially of the reflector, and also in the separate bracket for supporting the lamp.

The reflector 3- is secured at its apex by a screw 13- to the central portion of the back of the case -1- and flares outwardly toward the closure --2-, its outer end terminating in substantially the same plane as the front of the casing -1 and is of substantially the same diameter as the interior diameter of said casing, thereby cfi'ectually concealing the bracket 5, uhich is located between the reflector and easing. This reflector is provided with a radial opening through which the lamp socket -7 and lamp -8' project, the opening 1.4- being a limited radial and axial adjustment of the lamp relatively to the reflector.

The lid or movable front --2 is hinged at -1 5- to suitable lugs upon the periphery of the case l-' and its diametrical opposite side is provided with a spring-catch --l(5---- adapted to interlock \zith a recess --'l7- in the adjacent side of the case -1- to hold the door in its closed position and to permit it to be readil opened to obtain acinterior 0. the casing for the repair or adjustmcnt of the lamp. or other intorior parts.

l. A headlight comprising a casing, a hinged cover attached to the from of the casing, a conoidal-shapcd roller-tor arranged within the casing and extending from the front to the roar thereof, said reflector abutting against the back wall of the casin of the casing, said reflector haviru an opening in the top thereof, an inverted L-shaped bracket arranged within the casing above the rcllcctor and having the vertical arm thereof extending in parullclisn'i uith respect to the rear wall of the casing, means for of some-what greater diameter than that of the lamp socket or lamp to allow for emcee the o enhrg in the reflector, means for secure bracket in its adjustable position to the casing and an incandescent electric lamp extending through the opening in the reflector and adjustably secured to the portion to the horizontal arm of said bracket. of the bracket hich extends across said 2. A headlight comprising a circular casopenin ing having a movable closure, a reflector rear wall of the casing, a lamp socket extending through said 0 enin and carrying a lamp arranged Wit in t e reflector, and

adjustably connecting the bracket to the l means for adjustably connecting the socket In mtness whereof I have hereunto set my secured to and Within the casin separate E hand this 8th day of'June 1907.
